Abstract

An adhesive sheet is disclosed including a flexible substrate and an adhesive layer formed on at least one of the main surfaces of the flexible substrate. The adhesive sheet further includes a plurality of microscopic holes connecting the opposing surfaces of the sheet and being generally perpendicular to them. Such adhesive sheet is permeable by air and allows good bubble escapability when the sheet is applied to an article. Sufficient permeability of the sheet to air is achieved with microscopic size holes installed in modest areal densities, hence the appearance and functionality of the film surface are not significantly adversely impacted. One intended use of the subject invention is for tinting films used to reduce light transmission in windows for use in buildings and automobiles. In this application visual appearance of the film is paramount. Another intended application of the subject invention is for antireflective film which is applied to electronic computer displays (flat panel, cathode ray tube) to reduce unwanted ambient light reflection and to improve contrast.

[0003] Not Applicable FIELD OF THE INVENTION

[0004] The present invention relates to an adhesive film in a form of a sheet, strip, tape, label, tag, and the like which is perforated with microscopic holes to provide good air bubble escapability while maintaining good appearance and functionality of the film surface after being adhered to an article. BACKGROUND OF THE INVENTION

[0005] Various types of adhesive films comprising a flexible substrate and an adhesive layer have been heretofore available. Such films are provided in the form of sheets, tapes, strips, labels, tags, and the like. Those films having a pressure sensitive adhesive layer generally are mounted on some type of release liner or other releasable support to protect the pressure sensitive adhesive until the film is ready to be applied to an intended article. The film is then stri...
